STEAM-GENERATOR.

Specification of Letters Patent.

Patented Aug. 24, 1920.

Application filed March 17, 1919. Serial No. 283,177.

To all whom it may concern:

Be it known that we, ROLAND l3. MAN- NING and Len R. Moore, citizens of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Stean1-Ge11erators, of which the following is a specification.

This invention relates to new and useful improvements in steam generators.

The object of the invention is to generate a volume of steam in an economical and eflicient manner with a minimum fuel con sumption.

In carrying out the invention a plurality of generating fingers or tubes are disposed in the path ofthe heat arising from a suitable fire. Water is introduced in the lowermost fingers and is generated into steam which travels upward through connections between the tubes and is carried off for use.

Other details will be more specifically pointed out together with novel features and modifications.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown and wherein:

Figure 1 is a vertical sectional view,

Fig. 2 is a vertical sectional view at right angles to Fig. 1,

I Fig. 3 is a rear elevation of the generator,

Fig. 1 is a cross-sectional detail on the line 4 .2 of Fig. 3,

Fig. 5 is a cross-sectional detail on the line 55 of Fig. 3,

Fig. 6 is across-sectional detail on the line 66 of Fig; 2, i

Fig. 7 is a vertical sectional view of a modified form,

"Fig. 8 is a vertical sectional view of the same at right angles thereto, and 1 Fig. 9 is a cross-sectional view on the line 9-9 of Fig. 7. In'the drawings the numeral 1 designates an inclosing structure which may be built drum 4 is embedded in the rear of the structure. r From the face of the drum generating fingers or tubes 5 extend forward and terminate near the front wall. The front ends of the fingers are closed and said fingers are disposed in series or courses, each at a differ ent elevation and each course including a plurality of-fingers. On the outer side of the rear wall of the drum transverse hollow bosses or conduit (3 and 7 respectively, are cast insuperposed order. The bosses are opposite the rear ends of the fingers. A horizontal partition 8 is arranged between boss 6 and the lowermost boss 7. This partition forms a separate chamber in the lower portion of the. drum.

A water manifold 9 has branches 10 entering the front ends of the lowermost fingers and provided with spray-caps or heads 11. The water under pressure sprayed into the front ends of the lowest course of fingers. The steam and water from the lowest course of fingers is dis charged into the drum below the partition. The said steam and water enter the boss 6 through a slot 12 (Figs. 2 and 5) and pass to a riser 13 cast on the rear face of the drum and communicating with each of the bosses 7 through a valve seat 14L. A valve 15 is provided for each seat and is controlled by a hand wheel and stem 16 so that the supply to any particlar boss may be cut off if desired.

. Spray nozzles 17 screw into the rear wall of the drum so as to communicate with the bores of the bosses7. These nozzles are con siderably less in diameter than the internal diameter of the fingers into which they project. Spray caps or heads 18 are mounted on the forward ends of the nozzles, a short distance from the closed ends of the fingers. The water and steam from the riser flows into the bosses and through the nozzles to the caps 18. The spray ejected from the caps 18 contacting with the heated fingers forms a vapor which travels rearwardly in the fingers to the drum.

A steam outlet pipe 19 leads from the top of the drum to a storage tank 20 from which a supply pipe 21 extends. Bali'le plates 22 extend transversely of the structure 1 between the courses of the fingers in staggered is thus I tends to reverse the pressure in the fingers,

thus drawing water back through the perforations of the caps 18 and removing deposits from the inside of the same. I Figs. 7 to 9 we have shown a modified form in which the fingers 5 screw direct into horizontal pipe members embedded in a back wall 31 and connected centrally by short pip'es32'to1'1n-ing a riser extending'througl'i allot the members. A stock leads from the top fot the inclosing structure 1. water feed pipe3e: enters the bottom member 30 and' includ'es alcut-ofi' valve 35. A steam pipe 36 leads from the top member to a tank orfreceptacle 37 A return pipe 38 leads from the tank to-the pipe 34: for conveying' the condensation back to the generator. 'Itisobvious that the pipe 36 may lead to a point of use of the steam and the pipe 38 may return from said point so that a circulatory system is had and' the same water used over again, provided no steam is exhausted.
